The change of land use is an essential source for the growth of carbon emissions.Considering that intensive land use is an important mean to replace extensive land use, it is significant to clarify the relationship between intensive land use and carbon emissions to achieve carbon peaking and carbon neutrality goals.Based on accountings of carbon emissions and levels of intensive land use in Beijing-Tianjin-Hebei region from 2002 to 2017, the spatial and temporal evolution, relationships between them and their influencing factors are studied by using the standard deviation ellipse method, the decoupling theory and the geographic probe.The results of the study indicate that the standard elliptical distribution pattern of intensive land use and carbon emissions both show a northeast-southwest trend, in which the spatial pattern of intensive land use is high in the east and low in the west, and high in the south and low in the north; 62% of cities have experienced decreasing trends in carbon emissions.The Beijing-Tianjin-Hebei region have already been in relatively desirable states of strong decoupling and weak decoupling between intensive land use and carbon emissions.The interaction of all driving factors is quite remarkable, and the post-interaction is superior to the single-factor effect, among which the economic investment factor and land investment factor had the highest degree of reciprocal effect, and the internal factors of land investment had the weakest driving effect after the interaction.The study concludes that the intensive land use and the carbon emission in the Beijing-Tianjin-Hebei region are already in a relatively desirable state of strong and weak decoupling, and the relationship between the high driving factors and the general factors which influence the growth of carbon emissions should be dealt with properly during the process of land use in the future.
